Vaginal Ordor

I don't want to give TMI about it but I have realized that during sex, there's always a smell coming out from my vagina and it smells really unpleasant. Does anyone know why it does that or any treatment for it to stop smelling like that.

I have read all the basic treatments but it doesn't seems to help since I do shower every day, having a good diet with fruits and veggies, drink lots of water...etc. But the problem doesn't seem to go away. Please help 😣
